SPRING MATTRESS.

Application filed September 25, 1925.

This invention relates to bed springs or spring mattresses, the object of the invention being to provide a simple, inexpensive and effective means for stabilizing the side edges of the spring and thereby preventing the same from permanently sagging.

Bed springs, as commonly constructed, whether of fabric or spiral spring form, are approximately six feet in length and consequently it has been extremely difiicult to stretch the fabric when the spring is of this form sufficiently taut to prevent the sagging of the side edges, and when the spring is made of spiral springs it is practically impossible to make these springs along the side edges suiiiciently rigid to prevent this sagging, since so to do would interfere with the proper resiliency of the mattress. Consequently in the use of the spring the side edges sag and become permanently set, especially as it is common practice to sit upon the side edges of the bed at about the middle thereof and thus cause the spring to sag and get out of shape, materially interfering with the sleeping qualities of the mattress.

Therefore the present improvement has to do with means that will prevent a permanent set or sag in the side. edges of the spring without interfering with the resilient qualities of the spring mattress.

The present improvement, while permitting the proper yielding of the mattress along its edges, as is necessary to insure the proper resiliency of the spring mattress, is however, effective to maintain the side edges in their proper position when the weight of the user is spread along the entire side. of the spring and yet will permit the spring to yield at its edge when this weight comes at any particular point, while returning the spring to its normal position on the removal of such weight, and thus stabilizing and preventing the. permanent sagging and setting of the side edges of the spring.

In the drawings accompanying and forming a part of this specification, Fig. 1 is a vperspectlve view of one form of spiral spring having this improvement attached thereto; Fig. 2 is a side view of such form of spring; and Fig. 3 is a detail enlarged view of the stabilizer attached to a spring, illustrating the same in different positions, the dotted lines illustrating the action of the stabilizer when the side edges of the spring are under weight.

Serial No. 58,503.

Similar characters of reference indicate corresponding parts in the several views.

Before explaining in detail the present improvement and mode of operation thereof, I desire to have it understood that the invention is not limited to the details of construction and arrangement of parts which are illustrated in the accompanying drawings, since the invention is capable of other embodiments, and that the phraseology which I employ is for the purpose of description and not of limitation.

To illustrate the present improvement, spring or spring mattress commonly termed a spiral spring mattress is shown, which as is well known, is composed of many coilec springs located vertically side by side, and while this improved stabilizer is particularly adapted for this form of spring, it can also be used with other forms of springs.

The spring shown comprises the usual supporting frame 2 including the side bars 3 for resting upon the side bars of the bed structure, and which side bars are usually connected by suitable transverse members or bars 4: for vertically supporting the. spiral springs 5, Which are suitably connected or tied together, in the present instance by cross spiral springs 6; Along the edges of the spring the spiral springs are tied to a suitable reinforcing rod or strengthening member 7. The means for preventing the permanent sagging or setting of the spring along its side edges and thereby stabilizing such side edges of the spring, comprises in the form shown a spring acting or resisting means in the form of a rocking arm or lever 8, the upper end of which encircles as by means of a strap 9 the reinforcing rod 7. Intermediate the ends of this arm 8, it is pivoted as at 10 to an angle bracket 11 suitably secured or riveted as at 12 to the angle iron side bar 3. The lower end of the arm or lever 8 is connected by means of a coilec spring 13 to the bracket 11. These angle iron brackets extend inwardly toward the. longitudinal center'of the spring mattress and in consequence the arms or levers 8 project inwardly away from the side edges of the spring, so that they are out of the way and therefore there are no parts projecting beyond the. edges of the spring ma"- tress.

In practice, these stabilizers will be so constructed that they will have greater spdng resistance than each of the compression springs and will, in consequence resiliently support the side edge against sagging when the weight of the user is spread lengthwise along the side of the spring, as for instance, when the spring is being used for sleeping purposesin other words, will maintain the side edges of the spring substantially level with the rest of the spring-but when the weight of the user is brought upon any particular point, as when sitting upon th'cside edge of the spring mattress, these stabillzers will permit the side edges to yield sulliciently to insure the proper resilience of the mat tress, and when this weight is removed will return the side edges to their normal position, so that the stabilizers not only act to resiliently support the edge, but to prevent the permanent sagging and setting of such edge.

An desired number of these stabilizers may be used along each side edge of the spring according to the length of the spring, it being obvious that a shorter lengthof spring for childrens beds would require a less number of these stabilizers.

In the present instance a pair of these stabilizers are shown located along each side edge, being suitably and preferably equally spaced apart. In use it will be observed that the stabilizers maintain the upper side edges of thespring' mattress in a rigid but resilient condition, being of just sufficient re: siliency to permit the side edges of the spring to yield equally with the rest of the spring mattress. WVhen however, weight is placed along the side edges, at for instance, the middle thereof Where the greatest sagging usually occurs, the stabilizers will yield in accordance with the weight placed upon themattress, and when this weight is removed the stabilizers will return the side edge of the spring to its normal position, thus preventing a permanent sagging and setting of the spring. For instance, in Fig. 3 the dotted position of the arm 8 illustrates the movement thereof when the side edges of the spring are depressed while the full line position of the arm 8 illustrates the manner in which the side edges of. the spring are returned to their normal position by the spring operated stabilizer, and it will be observed that these locking arms or levers 8 move in the are of a circle while the springs connected thereto act transversely to the vertically supported compression springs forming the spring mattress. I
